■Power save function
The power save function conserves the boat’s battery power by pausing the transmission. The standby (pausing) times are selectable (rotation number is fixed to 10).
For example, when 1 min. is selected, the scanner ro- tates 10 revolutions; then stops for 1 min., and then re- peats this sequence while the power save function is activated.
